You passed the test. Timo, L.Ketola and the other is...I don't know. The pic is from the Smash-Tennis-Club-site. Maybe it's a coach from this club. At least it looks like he's explaining something.
btw Timo is still alive, I've found a score of a match he has won for Smash-Tennis last week.
I hope this pic will be part of that PGT-game here in the forum so that I've a chance to win.
